My Mother gave me a leather chair. She was a heavy smoker and I could not get the smell out of that chair. I tried Febreze (did not work) and even a odor remover that I buy from a janitorial supply company. The odor remover would last for a few weeks and then the smell would come back. I think it would slowly come from the stuffing out through the leather. I finally gave it away. Maybe call an upscale furniture store or high end rug store and ask for recommendations. Also places that advertise that they clean after having a fire or water damage might be able to remove the smell.

I'm not familiar with the exact odor produced by Holy H*** : ) but if it's anything like pet urine, you're right to be concerned. Assuming that some sort of protective urethane was used, sanding them down and restaining may work. If the stain has broken down at all because of age and the substance seeped into the wood it may not be that simple. I would find a furniture refinisher in your area and call and ask or even show them the chairs. It would be a shame to get rid of them - I hope you have some luck.

We have to research everything these days. I have been shopping for new leather couches and found this out today. A judge is expected to order several retailers to pay millions of pounds to people who suffered burns and rashes from faulty leather sofas. http://www.dvorak.org/blog/2009/05/20/toxic-leather-sofas-from-china/ After investigation, it was found that the couches were packed with sachets containing dimethly fumarate DMF, an antifungal agent intended to prevent the leather from getting moldy during storage and shipment from China. The chemical evaporates, penetrating the leather and can transfer to clothing and skin. Even small levels of exposure can cause serious skin sores, blisters, rashes and eye irritation. And some victims have reported that their problems have persisted long after the couch has been put on the curb. http://blogs.consumerreports.org/safety/2009/05/toxic-sofas-couches-rashes-chemical-burns-britain.html "Caveat emptor" (Let the buyer beware.)

If returning isn't a possibility then I would cut a foot or so off one of the rolls and aggressively air and dry it to see if that changes the odor. Do you see any signs of mold colonies? If not, it may be that it was just stored in a dampish, air-less place and has acquired that smell, but not actual fungal infection. Wallpaper, even new stuff, has a stale/musty smell to me. If a lot of air improves the odor noticeably, than that's what I'd do before hanging it. One technique that is sometimes used with books that have acquired a stale smell is to close them up with a 3-5" deep layer (on the bottom of a plastic container) of non-clumping kitty litter (the clay stuff, unscented and poured in, first, not over the item). For wall paper rolls I'd use a tall container like a clean garbage can with a tight-fitting lid (or seal it up with tape.) Put the rolls on a rack above the litter and never in contact with the litter. Leave it sealed for a few weeks. (Air and dry them well first and use the litter to draw out the remaining smell.) Some recommend doing the same thing with solid air fresheners, but those smell so foul to me it's worse than stuffiness and I think you are just covering the smell up. The true source of mustiness is slight dampness which responds well to airing and dehydration. I might even go so far as to loosely unroll the paper (so air can penetrate to all layers) and keep it in a dry area, or a room with a dehu going. You might also do a test hang of your cut-off sample to see if re-wetting it with paste (wallpaper paste is famously ideal mold-food) brings the problem back. Leave it on a sample board in your intended room to see if anything awful grows on it. Two caveats: both high heat (think ironing the paper) and freezing are sometimes recommended as cures for mold on paper. Aside from the risk of potential damage to the paper itself, both treatments have the possibility that they will create a rebound affect with resting spores of the mold, bringing it back worse than ever.
